About Mostap Sampling

First introduced by the GeoGroup as a service in 2017, MOSTAP soil sampling is a fixed-piston sampler which minimises soil disturbance and is able to obtain undisturbed samples of various diameters at any given depth. 

MOSTAP soil sampling involves driving a steel sampler into the ground using a standard CPT pusher rig. Once at the target depth, the MOSTAP is activated allowing the cone tip to stay stationary as the MOSTAP is advanced by one meter. The soil sample is captured in a sampling tube providing the user with a one-meter undisturbed sample of either a 35mm or  65mm diameter.

Some of the advantages of Mostap Sampling are:
  • You can obtain undisturbed soil samples which are essential for accurate soil analysis.
  • The Mostap sampler can be used in a variety of soil types
  • It's a safe and effective geotechnical testing method.
